It's good to hear that you are moving to MSA2050 but there is no comparison between P2000 performance and MSA2050 because both are different type array. P2000 is linear and MSA2050 is Virtual array.
You can check Vdisk Performance details on Page no 99 in SMU guide,
https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c02520791
Also you can check in below guide,
If your requirement is to check MSA live performance then better to check from CLI commands couple of times,
# show controller-statistics
# show disk-statistics
# show host-port-statistics
# show vdisk-statistics
# show volume-statistics
The one which you are trying is to check historical data only. May be you can try different time interval in past to get the data.
Hope your array is running with latest firmware TS252P005. If not then upgrade to latest.
Hope this helps!
